oIL BURNER- Application mea March 1'1, 1925.v serial Np. 14,6'32.

To alt whom t may concern.' l

Be it known that I, Louis OLsoN, a citi-v zen of the United States, residing at Enumclaw, in the county of King and State of tion is to provide an oil burner' of simple construction and embodying oil and flame spreading features not heretofore used, which may be used in the fire box of a locomotive with the most efficient result. Y

`It is well known in this art that oil burn ers adapted for use in locomotives are conf structed with but a single jet for feeding the fuel oil. The objection to such burners is obvious, and it is to overcome undesirable features, such as burning on one side of the fire box, ineffectively directing the flame when the engine leans, and many other objections, that this invention has been conceived and given the particular form shown herewith.

A further object of the present invention is the provision of a novel means for distributing the fuel oil to an elongated outlet, and heating the same as it is being distributed and forced from the supply inlet.

Au even further object of this invention is the contemplation of a baffle member which may be-carried by the burner to act upon the flame and cause the same to spread throughout the fire box.

T he several points of invention may be incorporated in structures of widely different types. and it is illustrated in a preferred form in the accompanying drawings in .and pressure fluid outlets.

Fig. 6 is a planview of the burner with' the Vcover removed and showing the diverging grooves.

Fig. 7 is a fragmentary section of the blodck taken along line VII-'VII of Fig. v3,

Fig. 8 is another fragmentary view of the block taken online VIII- VIII of Fig. 3.

Like reference characters refer to like parts throughout the several views in which the burner has been shown installed' in a locomotive E and constructed of any suitable material to define a block 9, hav-ing a f longitudinally extending pressure fluid passage 10, whichcontinues from a fluid inlet 11, provided at one end of the block 9, to an outlet slot 12 atrthe opposite end thereof. Steam may be introduced through passage k by the way of inlet 11 by any Vsuitable means such as the pipe 13, and the flow of s the same controlled by the ordinary valve not here shown. A cover 14 should be removably secured to block 9 by bolts l15 to permitof easy access to oil passages 16, which is provided, as shown, above pressure fluid passage 10, with partition 17 having concave grooves 18 along the bottom of the groove. These grooves 18 extend from a comparatively narrow portion adjacent oil inlet 19 to the wider oil outlet 20, at the opposite end and above outlet 12, in a diverging manner as shown in Fig. 6. These grooves distribute the flow of oil along outlet 20 and evenly spread the same in a thin sheet in passage 16, after entering through pipe O, to more readily receive the heat imparted to partition 17 from the steam in passage 10.

That portion of passage 16 adjacent outlet 20 is curved downwardly as at 21 to direct the iiow of oil across steam outlet 12 and against bajile member 22. Member 22 performs an important function, in that it narrows outlet 12 to the desired size by par,- tially covering the same and presents a series of transverse serrations 23, which spread the flame throughout the fire box.

VSide walls 24, diverging in continuation of diverging grooves 18, also directthe flame in a desirable manner. It is preferred to make the baffle member 22 a separate unit p of the burner and attach the Same to block 9 by bolts or analogous means 25, but other methods of construction may be adopted without departing from the scope of the invention.

By making this baie'22 a separate and removable unit, the same may be interchanged with ones of various thicknesses to alter or vary the size of the passage 12. This feature is important, and baflies of various thicknesses should be tried until passage l2 is of a size best adapted for the steam pressure with which the burner is to be used.

It should be particularly noticed that the passages 1() and 16 as Well as outlets 12 and 20 are very wide and the oil and pressure fluid is'not confined t`o small round jets but spread to a considerable Width at the point of atomiization and combustion.

They operation and novel features of the burner are obvious, and it is desired to be limited in the construction and embodiment of these points of invention, only by the prior'state of the art and the appended claims.

What is claimed is:

1. An oil burner comprising a block having a pressure fluid supply inlet and an oil supply inlet at its one end, separate passages continuing from each of' said inlets formed Within said block, extending longitudinally thereof and terminating in outlets formed at the opposite end, a baffle member supported by the block and disposed to partially restrict the fluid supply outlet, the Walls of said oil passage being formed at its outlet end to curve toward the said pressure fluid outlet and said baffle member, the oil directing surfaces of said Walls being curved concentrically.

2. An oil burner comprising a block having a pressure fluid supply inlet and an oil supply inlet at its one end, separate passages formed Within said block, continuing from each of said inlets, extending` longitudinally thereof and lterminating in outlets formed at the opposite end of said block and a baffle member having' transverse serrations supported by the block adjacent said outlets, said oil passage being formed adjacent its outlet to direct the flow of oil across the outlet of said fluid supply passage and against the serrations of said baffle member when oil is forced through its passage under pressure.

8. An oil burner comprising a block having a pressure fluid supply inlet and an oil supply inlet, separate passages formed Within said block continuing from each of said inlets to outlets formed by said block, said oil passage overlying said pressure fluid supply passage and having a plurality of concave grooves in the bottoml thereof entending from said oil supply inlet to said oil outlet and a baffle plate supported by said block in operative relation to both of said outlets, said oil passage and grooves being angled downwardly adjacent the oil outlet.

in testimony whereof I hereunto affix my signature this 2nd day of March, 1925.

LOUIS OLSGN.
